BIPALIIDAE 
1. Bipalium jalorense, sp. nov. 
One specimen, from the interior of a rotten tree-trunk lying on the ground. 
Bukit Besar, borders of Jalor and Nawngchik. 2,500 feet. 
Very distinct from any species hitherto recorded from the Peninsula. 
Unfortunately the only specimen has lost its hinder end, but the characters 
are sufficiently well marked to admit of a satisfactory diagnosis. 
The length of the fragment is about 30 mm., the breadth 5 mm. The 
breadth of the head is about 8 mm., and that of the ‘ sole ’ i mm. The mar- 
gin of the body is bright yellow. The middle of the dorsal surface is occupied 
by a longitudinal dark band about 3*5 mm. in breadth, which is nearly black 
laterally, but becomes slightly paler towards the middle line. The under 
surface has the margin yellow (the whole side of the body being of this colour). 
This margin is about as deep as on the dorsal surface. Within the margin on 
either side is a black band about i mm. in width, fading on its inner side to 
yellowish-white. The sole is white. 
The margin of the head and its lobes are yellow, thickly studded, 
especially towards the middle line, with minute eye-spots. The margin is 
about I mm. in breadth, and is succeeded by a well-defined, thick crescentic 
line of about the same breadth as itself, which commences on the under 
surface of the body, just behind the angles of the lobes, and is in turn followed 
by a small semi-circular patch of yellow, which intervenes between the 
crescentic black line of the head and the median black band of the body. 
The eye-spots on the margin of the head are so numerous as to give it a 
brownish tinge. Those lying along the extreme edge of the margin are 
decidedly smaller than those lying further back. Eye-spots occur also on the 
ventral side of the black marks in the angles of the lobes.
